Application i'led May 13, 1908. SeriaI No. 432,614..

To all 'whom it may concern:

Be it known that l, SHBRMAN Panni', a citizen oi the United States, residing at Orcutt, in the county oi Santa Barbara and State f California, have invented new and useful Improvements in Pumps, et which the following is a speciiicatien.

This invention. relates to pun'iping outfits the object oi the invention being to provide pnmping outfit in which all of the parts are readily accessible and easy el' repair, the parts being so combined as to enable the eperative elements to be tripped or disengaged from the well tube and withdrawn therefrom.

A further object of the invention is to construct the pumping outfit in such manner as to adapt the same for high speed work without danger of parting or breaking the rods; also te adapt old and partially worn wire place of employing new iron er wood rods. y

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein Vfully described, illustrated and claimed.

In the accompanying drawings :Figure l is avvertical longitudinal section through a portion el: a well, showing the pumping outfit therein, Fig. 2 is an enlarged vertical scctional view oi'l the upper union. Fig. 3 is a similar view of the lower union. Fig. 4 is a cross section en an enlarged scale taken above the barrel cap and through the upper union. i

Referring to the drawings,'1 designates a well tube which is made up el" sections which are shown as connected by an upper union 2 and a lower union 3. Tv'ifvithin the well tube 1 is arranged a working barrel 4 which is previded with a feet valve 5 in the form et a ball movable relatively to its seat 6 which is carried by the tubular holder 7 inserted in the lower end of the working barrel as shown in Fig. 1. The upper end oi" the working barrel is provided with a barrel cap 7/ which is' threaded inte the upper end et the barrel as shown in Fig. 1 and provided with an irregular opening 8 for the reciprocatory movement of the piston rod shown at 9. rlhe rod preferably consists of a cylindrical body pertion to which the reference numeral 9 is applied and eppesitely extending wings or rods 10 to prevent said rod from turning in the cap 7', the specific shape of said rod in cross section being illustrated in Fig. 4 and the opening 8 in the cap 7 being el cerrespending` shape.

rlhe upper union 2 is provided upon the inside with a spiral thread 11 adapted to engage a correspoin'ling thread or shoulder or plurality ei shoulders 12 on the outer side of the working barrel near the top thereof as shown in li 1 se that by turning the working barrel, said shoulder 12 may be moved inte and out of engagement with the spiral thread 11 for the purpose of locking the working barrel and allowing the same to be turned out oi the well tube er conversely locking said working barrel in its operative position by reason of the engagement between the shoulder 12 and the spiral thread 11.

The lower portion of the piston red 9 is reduced to ferm a cylindrical stem 13 around which is placed a coil spring 14 the lower end oi which is received in a spring seat 15 while the upper end bears against an upper spring seat 16 mounted in a limited sliding movement within the werking barrel, said seat being provided with a tubular pendent extension 17 having the lower edge thereof outturned to i'orm a circumferential flange 18 which in the upward movement of the valve rod comes in contact with an inturned flange 19 within the working barrel thereby iorming a stop ier the upward movement. The working barrel may be made up of any de sired number of sections one of the joints between the sections being shown at 20.

The lower end ei' the piston rod is internally threaded to receive a threaded shank 21 on the upper end et the pump piston in the form of a valve cage 22. Within this cage is mounted a plunger valve 23 shown in the forni oi' a ball which rests on a valve scat 24 carried by a tubular holder 25 removably inserted in the lower portion oi the valve cage as seen in Fig. 1. The valve cage is shown as jointed at 26 to provide two sections which are removable one from the other to give access to the valve seat and to provide for the removal oi the valve 23.

The lower union 3 is provided with an interior barrel seat 27 having an inclined upper surface with which cooperates the corresponding inclined `face of a barrel shoulder 28 fast en the working barrel 4. At its upper end the valve red is provided with a socket extension 29 adapted to receive and held the lower enlarged end of the operating wire or cable 30.

lt Will be understood that by twisting or turning the Wire 30, the lugs or shoulders l2- on the Working barrel may be disconnected from the Spiral thread 1l Within the upper union 2 so as to admit of the removal of the operative elements of the pump and con- Verselj,T by turning the Wire in the opposite direction, the lugs or shoulders 12 may be reengaged with the spiral thread l1 therebyr l the Well tube and Working barrel adapting' locking` the operative elements of the pump in their Working positions.

l claim 1. A Well pumping outiit comprising a Working barrel, a cap at the upper end thereof, a Jfoot Valve at the lower end thereof, a

piston comprising a Valve and a cage movable up and down Within the Working barrel,

a piston rod passing through the barrel cap and engaging the same so as to turn the cap with it, a projection on the side of the Working barrel, and a Well tube having an internal spiral thread With which said projection is adapted to engage in the turning movement of the Working barrel, substantially as described.

rhe combination. with a Well tube, of a Working barrel mounted therein, a piston rod engaging said Working barrel so as "to turn therewith, and interlocking means on the Working barrel to be engaged With and disengaged from the Well tube to permit the Withdrawal of the Working barrel.

n testimony whereof afllx my signature in presence of two Witnesses.
